Because of its color display is great.
Voltmeter is very accurate, the accuracy is + – 0.1V
Has a long lifetime (I sold them 100 + and only one broke down)
Voltmeter can be placed into the panel has handles.
Shows one place after the decimal, which is a condition accurate measurement ..
Some voltmeters can calibrate voltmeters all look the same, but the PCB is different anyway, all PCB accurate +-0.1V
Voltmeter can working in two modes
The first mode is Self powered
Voltmeter can be powered from the same source and the source of the measured
Voltmeter range in self-powered mode is 4.5V – 30V
The second mode is with external power
External power supply with selectable voltages from 4.5V to 30V . External power supply is connected to the red and black wires .
The measuring range is 0 – 100V . Yellow or white wire conect to board with plus for measured source 0-100V (0-99V).
Other technical information about 0-100V Digital Voltmeter
- Dimensions: 48mmx29mmx2.2mm (L x W x H)
- Power suply 4.5V-30V
- Wide measurement range 0-100V
- Red Blue or Green LED display
- Low power consumption
I have good experiences with ebay sellers and Tinydeal or Buyincoins chinese eshops.Price for voltmeter is about 2-3usd include shipping (free shipping)
Voltmeter can use to mesauring voltage on car battery (selfpowering mode) Electric bike , battery arays (0-100V), Photovoltaic panel and other DC voltage devices with voltage 0-100V.
